一、同步Centos各版本源

1.配置repo文件

• 以6.0为例

vim /etc/yum.repo.d/CentOS-6.0.repo
#贴入下方配置文件
## centos6.0
[base6.0]
name=CentOS-6.0-os-local
baseurl=http://archive.kernel.org/centos-vault/6.0/os/x86_64/
gpgcheck=1
gpgkey=http://archive.kernel.org/centos-vault/6.0/os/x86_64/RPM-GPG-KEY-CentOS-6
#released updates
[updates6.0]
name=CentOS-6.0-updates-local
baseurl=http://archive.kernel.org/centos-vault/6.0/updates/x86_64/
gpgcheck=1
gpgkey=http://archive.kernel.org/centos-vault/6.0/os/x86_64/RPM-GPG-KEY-CentOS-6
#additional packages that may be useful
[extras6.0]
name=CentOS-6.0-extras-local
baseurl=http://archive.kernel.org/centos-vault/6.0/extras/x86_64/
gpgcheck=1
gpgkey=http://archive.kernel.org/centos-vault/6.0/os/x86_64/RPM-GPG-KEY-CentOS-6

#运行如下命令
yum repolist

2.多个repo文件

• 多版本解决方案

[root@local]# ls
CentOS-6.0.repo   CentOS-6.1.repo  CentOS-6.3.repo  CentOS-6.5.repo  CentOS-6.7.repo  CentOS-6.9.repo
CentOS-6.10.repo  CentOS-6.2.repo  CentOS-6.4.repo  CentOS-6.6.repo  CentOS-6.8.repo
[root@]# yum repolist
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
repo id                       repo name                           		status
base6.0                       CentOS-6.0-os-local            		     6,019
base6.1                       CentOS-6.1-os-local             		    6,188
base6.2                       CentOS-6.2-os-local            		     6,294
base6.3                       CentOS-6.3-os-local            		     6,346
base6.4                       CentOS-6.4-os-local            		     6,381

base6.7                       CentOS-6.7-os-local            		     6,575
base6.8                       CentOS-6.8-os-local            		     6,696
base6.9                       CentOS-6.9-os-local            		     6,706
extras6.0                    CentOS-6.0-extras-local        		         1
extras6.1                     CentOS-6.1-extras-local        		         3
extras6.2                    CentOS-6.2-extras-local        		         6
extras6.3                    CentOS-6.3-extras-local        		        17
extras6.4                    CentOS-6.4-extras-local        		        13
extras6.5                    CentOS-6.5-extras-local        		        15
extras6.6                    CentOS-6.6-extras-local        		        38
extras6.7                    CentOS-6.7-extras-local        		        64
extras6.8                    CentOS-6.8-extras-local        		        64
extras6.9                    CentOS-6.9-extras-local        		        53
updates6.0                    CentOS-6.0-updates-local  		           1,042
updates6.1                    CentOS-6.1-updates-local   		          1,253
updates6.2                    CentOS-6.2-updates-local  		           1,154
updates6.3                    CentOS-6.3-updates-local  		           1,233
updates6.4                    CentOS-6.4-updates-local  		           1,555
updates6.5                    CentOS-6.5-updates-local  		           1,608
updates6.6                    CentOS-6.6-updates-local  		           1,370
updates6.7                    CentOS-6.7-updates-local  		           1,622
updates6.8                    CentOS-6.8-updates-local  		             974
updates6.9                    CentOS-6.9-updates-local  		           1,308

3.同步脚本

同步命令如下：

vim update-yum.sh

# update-yum.sh的内容如下

#!/bin/bash
reposync -n --repoid=extras6.0 --repoid=updates6.0 --repoid=base6.0 -p /data/centos/6.0
reposync -n --repoid=extras6.1 --repoid=updates6.1 --repoid=base6.1 -p /data/centos/6.1
reposync -n --repoid=extras6.2 --repoid=updates6.2 --repoid=base6.2 -p /data/centos/6.2
reposync -n --repoid=extras6.3 --repoid=updates6.3 --repoid=base6.3 -p /data/centos/6.3
reposync -n --repoid=extras6.4 --repoid=updates6.4 --repoid=base6.4 -p /data/centos/6.4
reposync -n --repoid=extras6.5 --repoid=updates6.5 --repoid=base6.5 -p /data/centos/6.5
reposync -n --repoid=extras6.6 --repoid=updates6.6 --repoid=base6.6 -p /data/centos/6.6
reposync -n --repoid=extras6.7 --repoid=updates6.7 --repoid=base6.7 -p /data/centos/6.7
reposync -n --repoid=extras6.8 --repoid=updates6.8 --repoid=base6.8 -p /data/centos/6.8
reposync -n --repoid=extras6.9 --repoid=updates6.9 --repoid=base6.9 -p /data/centos/6.9

执行参数

nohup sh update-yum.sh > log 2>&1 &

4.使用createrepo创建本地yum仓库

4.1 创建索引

#以一个为例，格式：createrepo -po 源目录 索引元数据的输出位置目录
createrepo -po /data/centos/7.4/base7.4 /data/centos/7.4/base7.4
createrepo -po /data/centos/7.4/updates7.4 /data/centos/7.4/updates7.4
createrepo -po /data/centos/7.4/extras7.4 /data/centos/7.4/extras7.4

4.2 创建组文件的索引

支持yum groupinstall ，也可略过

4.3 引入签名

wget http://archive.kernel.org/centos-vault/RPM-GPG-KEY-CentOS-7 -P /data/centos

二、建立本地yum源

2.1搭建http服务

安装apache

yum install httpd

配置

修改文件/etc/httpd/conf/httpd.conf

DocumentRoot "/data/centos"
<Directory "/data/centos">
  Options Indexes FollowSymLinks
  Options Indexes
  AllowOverride All
  Order allow,deny
  IndexOptions Charset=UTF-8
  Allow from all
  Require all granted
</Directory>

删除welcome配置

mv /etc/httpd/conf.d/welcome.conf /etc/httpd/conf.d/welcome.conf.bak

• 启动

systemctl restart httpd
systemctl enable httpd

2.2配置本地yum文件

• 客户端配置repo文件

[base7.4]
name=CentOS-7.4-Base-local
baseurl=http://10.x.x.x/7.4/base7.4/
gpgcheck=1
gpgkey=http://10.x.x.x/RPM-GPG-KEY-CentOS-7
#released updates
[updates7.4]
name=CentOS-7.4-Updates-local
baseurl=http://10.x.x.x/7.4/updates7.4/
gpgcheck=1
gpgkey=http://10.x.x.x/RPM-GPG-KEY-CentOS-7
#additional packages that may be useful
[extras7.4]
name=CentOS-7.4-Extras-local
baseurl=http://10.x.x.x/7.4/extras7.4/
gpgcheck=1
gpgkey=http://10.x.x.x/RPM-GPG-KEY-CentOS-7

三、同步任务

3.1同步任务脚本

• update.sh

#!/bin/bash
echo 开始同步centos7
reposync -n --repoid=extras7.4 --repoid=updates7.4 --repoid=base7.4 -p /data/centos/7.4
echo centos7同步结束
#更新元数据
createrepo --update /data/centos/7.4/base7.4
createrepo --update /data/centos/7.4/updates7.4
createrepo --update /data/centos/7.4/extras7.4

3.2 crontab设置

0 6 * * * /data/update.sh
